I would think 'fdformat' would work, but...

mtools expects there to be a low-level format available from the OS.
Thanks for any pointers here!
The other thing is: if I format on a different machine, when reading /
writing and some floppy HW error occurs, pretty much, the only way to
'clear' the error is to unplug the USB connector & plug it back in. The
machine more or less 'hangs' if, e.g., a sector has gone bad.
I know these questions are from a different era of computing, but, gosh, I
do really like the backward compatibility of NetBSD.
Thanks again,
